The resistor drops the power to the fan and the fan goes slower.

Why Fan only works on 3 speeds?

a fan only has 3 speeds because if it had gone any faster you would be blinded by the rapidness of the fan and if it had gone any slower there would be no point on even turning on the fan in the 1st placethis answer is brought to you by a 10 year old girl from new jersey your welcome


Why does the heat blower only work on low and medium but not on high?

It could be due to a faulty resistor in the blower motor circuit. The resistor regulates the speed of the blower motor, and if it malfunctions, the high speed setting may not work properly. It would be best to have a mechanic inspect and replace the resistor if necessary.


Why does the blower fan only work on high speed?

The blower motor resistor module is ruined and need replacement. It can be found from below and behind the glove box. Tt may be hard to see, follow the wires to connection that is mounted to the blower unit by two small hex-head screws. I removed the glove box so I could access it easier than trying to go from the bottom in a confined position.


Does current flow through a resistor, or does it flow across a resistor?

Current flows through a resistor, not across it.


Is it true the effects pf kinetic energy the slower and objecg goes the longer that it will take to bring that objecg to a stop?

Yes, that is true. The kinetic energy of an object is directly proportional to its speed, so the slower an object goes, the less kinetic energy it has. This means it will take longer to bring the object to a stop compared to if it were traveling faster.

What happens when the blower motor resistor goes bad?

What can happen when a blower motor resistor goes bad is that the motor will run and then suddenly stop running on a regular basis. Sometimes the blower fan will not turn on and cause the motor to overheat.

Where is the blower motor resistor on a 1997 Nissan Sentra?

The fan will always have power under normal conditions when on. The speeds are controlled by the resistor based on the fanf switch position. The resistor is located on the black plastic fan cover under the dash and behind the glove box. The cable harness goes right into it. Follow it. Remove the screws and the resistor side of the assembly is facing the air duct side of the fan compartment. Be sure to have the a/c off when working or you may damage something or burn yourself with the resistor.
